SPECIFICATION forming part of Letters Patent No. 644,258, dated February 27, 1900.' Application filed August so, 1898. Serial no. 659,865. (No model.)

To all whom it may concern.- 7

Be it known that I, ALPHONSUS GERALD OFARRELL, a subject of the Queen of Great Britain and Ireland, residing in the city and county of Dublin, Ireland, have invented new and useful Improvements in Paper-Carriers and Spacing Mechanism Applicable for Use on Type -Writers or Linotype-Machines and Telegraphic Printing and Recording Instruments, of which the following is a specification.

This invention relates to improved papercarriers and spacing mechanism applicable for use on type-writing or linotype machines and telegraphic printing and recording instruments; and its object is to provide suitable means or mechanism whereby, say, a sheet of paper maybe type-written upon continuously from end to end by, say, for example, any of the well known forms of type writing machines having the type mounted, say, on levers or bars or rings or otherswise, but without having to adjust the machine for each line.

In the drawings hereunto annexed, Figure 1 a part plan looking at the top of a typewriting machine constructed according to this invention; Fig. 2, a part end elevation of a machine; Fig. 3, a part front elevation of means employed for imparting a rotary motion to the platen-roller; Fig. 4, a part end elevation of escapement-operating lever; Fig. 5, a perspective back view, showing dog or escapement mechanism with upper framework of type-writer removed; Fig. 6, a perspective view of platen or paper-carrier applied to, say, a Remington .or similar machine.

Similar letters and nu merals refer to similar parts throughout the views.

A is a light frame supported and sliding backward and forward laterally on a second frame B for printing capitals by means of the bar I), as in the ordinary Remington machine and operated ina similar manner. In Fig. 2 I show a lever 1 connected to the bar I), and a connection 2, which extends to the shift-key on the keyboard. (N 0t shown.) The frame B is hinged at its back at B to the framework A for inspection purposes to the top plate of a machine, say, of the Remington or any other pattern. This arrangement may be modified to suit type-writing machines of almost every pattern. I I

C is 'a fixed spindle or shaft supported and its ends held in the bearing 0 of the frame A, with aportion of its length having a screwthread cut therein, as shown at c, Fig. 1. The pitch of the screw-thread equals, as a rule, the minimum space between two of the lines of type-writing.

D is a sleeve supported by and rotating on the fixed spindle O, having-its ends bushed for this purpose. The sleeve D is free to revolve on the fixed spindle O, and it (the sleeve) is provided with a slot d, cut therein for about, say, half its length in the direction of its axis, immediately over the screwthreaded part c of the spindle O. A feather d of or about equal length to the said screwthread 0' projects from the periphery of the sleeve D for purposes to be presently described. This feather cl is placed at an angle to the axis of the sleeve, as shown at Fig. 1.

E is the platen or carrier, hereinafter termed a platen, consisting of a cylinder or barrel mounted on sleeve D, and itis prevented from rotating independently of the said sleeve by means of the feather d, hereinbefore described; but it can slide lengthwise on the sleeve from end to end of the fixed spindle O. The platen on which the paper Ris placed is somewhat larger in circumference than the width of the sheet of paper for which the machine is intended to allow for it to be securely fastened to the carrier. The carrier is also somewhat longer than the sheet of paper. To the platen is imparted a revolving and traversing or, in other words, a screw motion, and it has motion for about its own length. It will therefore be obvious that if the platen be revolved over the strikingcenter of a type-writing machine an imaginary continuous spiral line similar to a screw-thread would be traced thereon.

F is a pin removable at will, but so arranged that it can be fixed in the boss f at end of platen. The pin F is made to pass through the slot (1 in the sleeve D and to gear into screw-thread c of the fixed spindle O for causing the platen to follow the course of the screw on sleeve D. Vhen the sleeve is caused to revolve, the platen will be made to rotate with it, and simultaneously the projecting pin F by its engagement with screw-thread a will force the sleeve D forward in a longitudinal direction, and thus a screw or spiral motion will be imparted to the platen E. The platen E and sleeve D are rotated by means of a band P on the sleeve, (shown in the drawings at Fig. 1,) byacounter-shaftL, and pulley P, such counter-shaft being driven or actuated by a weight, clockwork, spring, or other motor, a weight N being shown in the drawings at Fig. 2. The motionis controlled and proper letter-spacing secured by means of a toothed disk fixed to the sleeve in conjunction with an escapement or dog to be now described. H is a disk mounted and fixed to the said sleeve D. On the periphery of the disk H is cut a'number of teeth h, say, equal to the number of letters required to fill a line of printing on-the sheet R for every revolution of the platen E in addition to allowing the usual space for each letter as is usually provided in type-writing. A few of the teeth h may be omitted at h, Fig. 2, to leave a space which corresponds with the margin or lap of sheet where no printing is I required.

I is a small shaft arranged, say, at a right angle to the fixed spindle O and armed with a handle 1 capable of being rocked by means of bevel-gears I, mounted, respectively, on shafts I and J. The shaft J is connected by lever I and link X to the keyboard A, as hereinafter described. A spring I (shown at Figs. 2 and 4) is provided to return the shaft I to its normal position after each operation or stroke of the keyboard and on the release of the keys.

On the shaft I is mounted an escapement or dog consisting of two similar halves K K, formed of rather wide pieces of metal having their edges curved radially from the center of rocking shaft I and also formed to suit the shape of tooth on disk H. The portion K of the dog is always rigid, while its other part K has a tendency to advance in direction of arrow 1 on being actuated by means of a flat spring K (shown at Fig. 2,) which is capable of adjustment by set-screw K and thus forms a kind of spring pawl or dog. The part K of the dog is held normally in contact with the tooth by means of the spring 1 attached to rocking shaft I. This portion of escapement works as follows: The escapement when in its normal position is drawn toward the right by means of spiral spring 1 The spring part K is then in contact with one of the teeth h of the disk. By the superior force of the driving-motor, say weight N, itis forced into line with the rigid part K. In the action of pressing a key the shaft I is rocked toward the left, when the rigid part K of the dog enters the same tooth h that the spring part K has just left, thus preventing the disk moving while a character is being printed onto the paper R. The spring part K then being free of the disk 11 advances or springs forward to the right the distance of a tooth, which on pressure again from the keyboard being removed it enters before the rigid part K leaves its tooth. The recoil of the spiral spring I then causes the rigid part K to pass to the right, setting free the tooth which it has been engaging. As the rigid part leaves the tooth the movable part engages the next tooth following. The superior force of the motor-driven escape-wheel H'then overcomes the slight resistance of spring of movable part K, which is thereby forced into line with rigid part K, where it is retained. The escapementdisk H will have advanced the space of one tooth during the operation that is, for each stroke of the keyboard.

L is a counter-shaft arranged parallel with the fixed shaft 0, mounted in hearings on the framework A and having at one end a drum M, on which a cord N is wound. To the cord N is attached a weight or spring. A weight N is shown in the drawings at Fig. 2. At the other and opposite end of shaft L is mounted a disk 0, provided with three projections 0 0 0 on its periphery. These projections are designed to engage with an arm or pawl 1 mounted on shaft I, when it is drawn over sufficiently for the purpose by the keys A for marginal spacing. The pawl is clear of the teeth of the disk 0 normally; but on pressing or turning the hand-lever 1 (shown at Figs. 1 and 2) it is brought in front of the teeth of the said disk, when the main or rigid part K of the escapement-dog is completely withdrawn from the teeth It in the disk H, thus permitting the counter-shaft L to revolve until stopped by the first projection O of disk 0 coming into contact with the pawl or lever I.

The shaft L and the sleeve D are shown at Fig. 1 connected together by pulley P and band P in the proportion of three to one; but any other or equivalent form of transmitting motion, such as spur-gearing, to the said two parts may be employed.

A handle Q may be provided for winding up the weight and bringing platen E back into its normal and starting position.

R is the sheet of paper, secured on the carrier by means of rubber bands or clips 0'. (Shown in the drawings at Fig. 6.)

S is an alarm-bell, and T an adjustable pin mounted in slot T, cut in the face of the disk H, for striking the bell, and thus giving a signal prior to the end of each line being reached.

U is an additional or spacing lever provided at side of machine to which the escapementgear is connected and actuated by a link X, connected to lever 1 mounted on shaft J, as shown at Figs. 2 and 5. It is arranged so that it can be depressed by the keys A or the usual IIO spacing lever or bar Y by means of the projection y, fixed to the spacing-lever Y and acting upon the lever U for ordinary spacing, as shown at Fig. 6 but it can be still further depressed for bringing the arm I into gear and the portions of the escapement-dog K K out of action for finishing up the end of a paragraph. The lever Y is somewhat similar to the arrangement found in a Remington machine, and it is pivoted at the rear of the machine; but it is not directly connected to the spacing-gear, but acts through lever U by pressure by means of projection g, which acts on lever U, as just described. If desired, the handle I may be used in place of lever U.

The action of the machine will be bestseen with reference to the perspective views shown at Figs. 5 and 6. The paper R is mounted on the platen E, which is supported by the sleeve D, said platen being connected to the sleeve as described. The sleeve has on its periphery the long feather d, (shown at Fig. 1,) which insures that the platen and sleeve must rotate together. The platen is not prevented from moving lengthwise on the sleeve. About half of the sleeve has a fairly-wide slot d out in it, through which passes the pin F, which is carried by the bossf of the platen. The pin F gears into a screw 0 of the fixed spindle O, on which the sleeve D rotates. Consequently the rotation of sleeve and platen causes the platen to advance toward one end as it is rotated. In other words, the rotation 'of the arrangement would cause an imaginary screw-thread to be traced on the surface of platen or paper thereon, the pitch of which equals the pitch of leading-screw on fixed spindle. A sheet of paper R being placed on platen E and retained thereon, say, by rubber bands 1" and the arrangement fixed over the striking-center of, say, a Remington machine, as each letter is struck the sleeve D rotates with a step-by-step motion and a spiral line of printing is impressed on sheet. In placing the paper on the platen it is fixed somewhat askew, (dependent on pitch of thread of the leading-screw). This insures that when it (the paper) is removed the seemingly-continuous spiral line of printing resolves itself into a series of perfectly-parallel lines. The feather 01, above referred to, instead of being perfectly coincident with axis of the said sleeve is given a slight angularity, such angularity being dependent on the pitch and lead of the screw. The inclining of the feather d is for compensating any loss that takes place each time the platen makes a complete rotation and for insuring that the typewritten matter may be printed thereon in one continuous spiral line from end to end of the sheet. By placing the vertical edge of the paper on the platen parallel with the feather d, as shown in the drawings, it will be found that when the type-written sheet is received from the platen the type-written matter isin parallel line.

The sleeve .1) is provided at one end witha plied to a counter-shaft L immediately behind the sleeve D. The said sleeve and counter-shaft are connected together by a band P, arranged to pass over the pulley P, and being geared in the proportion of three to one. The weight N is wound up onto the pulley M, and the platen E is rotated to the left, which is the starting position, by means of handle Q, as shown at Figs. 2 and 6.

The escapement is effected by means of a dog somewhat similar to the well-known arrangement on the Remington machine, with the exception that in this invention the dog moves or rocks at right angles to the edge of the toothed disk H, before described. The action of the spring-section K and a permanent section K is exactly similar to that of the well-known dog-and-rack arrangement of the Remington machine-that is to say, no motion of the sleeve D takes place while the dog is pulled to the left by the action of striking a letter. On the release of the key, however, the dog is returned to the right or normal position by the action of helical spring 1 attached to small handle 1 whereby one toothspace of disk is allowed to pass at each stroke. The dog is mounted on the shaft I, on which is also mounted the handle 1 as well as the lever 1 and a bevel-Wheel I at its end. This bevel-wheel gears with a similar bevel-wheel I on a shaft J at right angles to first-named shaft I. The shaft J, which is at back of frame B and supported thereby, carriesa le ver 1 which is connected by link X directly to the spacing-lever U. Each time a key A is struck the lever U is pulled, the motion being transferred to dog-shaft I by means of bevel-gears 1. Thus the alternate or rocking motion is imparted to the section of the dog.

The type-writing machine is provided with a spacing-bar system similar to that usuallyemployed in the Remington machine, aprojection y, shown bearing on lever U, being provided in addition. The keys bear on a common bar Z, which is part of lever Y, and

IIO

which in turn transfers the motion to lever ment-disk II on the sleeve D. When the dog shaft I has been rocked sufficiently to the left by means of an extra depression of lever U, the dog then leaves the escapement-disk II completely, which in that case would rotate quickly till the platen E has been driven to the end of its traverse; but before the dog can completely leave the escapeme'nt-disk H the lever I is in position to intercept the first of the three projections on disk 0, and its motion is arrested. These projections O O O are so arranged that one will be at the lowwithout in any way affecting the escapement,

as the said parts thereof are attached to the frame A, as clearly shown at Fig. 6. In this movement from front to rear the shaft I moves also. The rearend of this shaft has a splined connection at 8 with the sleeve 5 of the beveled pinion I, which sleeve is journaled in the bearing or bracket 6, attached to the frame B. The sleeve 5 is held in the bearing by the collar 7. By this means the shaft I can move longitudinally through the sleeve 5 and bearin g 6 as the frame A is moved backward and forward, and thus the parts of this escapement carried by the said shaft I remain in engagement atall times with the ratchetwheel.

Having now particularly described and ascertained the nature of the said invention and in what manner the same may be carried into practice, I declare that what I claim as my invention, and desire to secure by Letters Patent, is-

1. In a type-writing or printing machine the combination of a shaft rigidly mounted in frame hinged to the top of the framework of the machine, a screw-thread cut in said shaft for a portion of its length, a sleeve mounted upon and free to revolve on said shaft, said sleeve having a longitudinal slot cut in it for a portion of its length, a platen mounted upon said sleeve capable of revolving with and sliding longitudinally upon said sleeve, a pin arranged to pass through a boss on the platen in the slot of said sleeve and to engage with the screw-thread cut in the fixed shaft, a disk mounted upon the said sleeve having teeth out in the major portion of its periphery, a recess formed in periphery of said disk between the said teeth, a rocking shaft armed at one end with a handle and at the opposite end with a bevel-wheel and provided below and at right angles to the fixed shaft, a helical spring for returning the rocking shaft to its normal position after each oscillation, an escapement-dog mounted upon said rocking shaft and consisting of a rigid section and an adjustable spring-"section, each of said sections being arranged to engage with the teeth out in the periphery of said disk, a second shaftarranged at right angles to the escapement-shaft and armed with a bevel-wheel arranged to gear with bevel-wheel on the lastnamed shaft, a lever mounted upon the second shaft, a spacing-lever, and a link for conneoting it to the lever on the second shaft, all as set forth.
